FULL FLOW: what oil port is drilled & tapped then plugged on my case?

[61SedanMan]

It isn't plugged...it gets a pipe thread (3/8 npt) and a barb or srew fitting. If you are looking at the rear of the motor, staring at the oil pump hole, you will see two holes on the inside walls of the oil pump hole. The one on the right is going to the pickup tube (it is sucking from this side). The one on the left is where it is pumping the oil. The left one is a holow galley going up and left at a 45 degree angle (give or take). You first need to tap and plug this hole. You will see the cavity from the rear of the block. Follow it up (maybe 2-3 inches) and you will see a plugged hole. This is the main oil galley. Drill out the plug and tap it 3/8 npt. Use an oil pump cover with an oil takeoff, filter it and cool it, and pump clean, cool oil into the main oil galley. Hope this helps.

Here's a question for ya. I noticed that Gene Berg sell a full-flow tap kit that they say can be used on an ASSEMBLED engine. Has anybody done this? I would like to full flow my new one, but don't want to dissassemble it. It has a filter pump and I'd rather go full flow.

The "trick" is to use grease on the tap and to remove the bypass plug and used compressed air to blow and metal out of the case.

It can be done, but i've never tried.

I tapped my winter engine assembled. But I extended the Berg procedure a little.

In addition to the drill and the tap, you will need compressed air, a shop vac, a medium sized shop towel and an assistant. No grease is involved.

1) Remove the low oil pressure switch and the oil pump.

2) Apply air to the pressure switch hole. That air will flow out through the oil galley where the oil pump was. That galley is the normal pump output.

3) Position the shop vac hose near where all that air is coming out. During the drilling and tapping, all the flakes will come out in that air-stream. The idea is to collect it all with the shop vac.

4) While your assistant mans the compressed air and the vacume, you do the drilling / tapping. When the drill bit breaks through, compressed air will cause magnesium flakes to cover the front of your shirt. Your assistant may find this amusing. But he only has a girly shop-vac while you have the manly drill so all is well.
